A cheap stereo microscope for fine pitch SMD soldering

When building my tinyFISH fc and the tinyPEPPER ESC I was faced with soldering 0402 sized components. That is quite tricky to do manually, a stereo microscope helps a lot! Do not go for a monocular scope, 3D relly helps a lot. As this is just a hobby project and I am running on a… Read More »

pepperF1SH – Part VII: a new 3D printed camera and battery mount

pepperF1SH This post is the seventh in a series of posts about the adventure of building the world’s lightest brushless FPV quadcopter: project pepperF1SH. I updated the camera and battery mounts as i decided to order them from Shapeways. I added the option to add a camera protector (aka cable tie) and thinned some walls.… Read More »

Using openocd and a ST-Link V2 to debug betaflight on a STM32F3

During development of my tinyfish FC i used the st-util gdb bridge for debugging. I had some issues using it, mainly unstable usb communication etc. Therefor i switched to openocd. Recently i have read a lot about the very nice blackmagic probe, the best part is that the firmware can be flashed into the cheap… Read More »
